You push your own arguments so much to the extreme that you completely miss the point. It evidently bothers you a great deal to actually see a character you are supposed to be playing. Probably so much, that you just can’t enjoy the game the same way as if it wasn’t there. Sounds like a pretty unenviable thing. But that doesn’t mean that everyone else just has to feel the same way or be a fool who doesn’t know what he’s talking about.
Some people just simply don’t see a problem about having the player character on the screen. Some people are just not bothered by that. Some people just don’t mind and really can (and really do) enjoy the game just as much in the 3rd as in the 1st person.
And some others obviously absolutely can’t and don’t. I feel kinda sorry for them, as it sounds pretty frustrating to me and I probably wouldn’t be able to play a lot of my favorite games, which don’t have any sort of 1st person, if I was this way.
If all the point you are trying to make is still just the fight-againts-the-idea-of-3rd-person-in-KCD, I’m actually all with you, but it’s really you who is getting a way off with his argumentation here.
